Answer key: Traditional IRA worksheet
Calcapedia 1. After-tax value at age 50: $67,118.15
Start with the 2026 IRA limit for people under 50
Your income is at or above $10,000.00, the top of the phase-out range, so none of it is deductible. You can still contribute
This year you put in your planned amount or the limit, whichever is smaller. The deductible part is capped at the deductible limit
The deduction lowers your taxable income, so it saves tax at your current rate
Each year the balance earns its return, then that year's contribution is added
Repeat that for 8 years to get the balance when you retire
Contributions you couldn't deduct were already taxed, so they come back tax-free. Only the rest is taxed
Withdrawals are taxed as income. At a 14% rate, this is the tax
Subtract that tax to find what the IRA is worth to you after tax
